How to Get from Koh Kong to Koh Rong Samloem

Last updated: March 8, 2026

Leaving the rugged mangroves and cardamon foothills of Koh Kong for the white sands of Koh Rong Samloem marks a transition from Cambodia's wild frontier to its most serene island paradise. While Koh Kong offers a glimpse into the country's eco-tourism heart, Koh Rong Samloem is where the pace of life slows down to the rhythm of the Gulf of Thailand's gentle waves. This journey takes you from the Thai border region down the coast to the pier at Sihanoukville, the gateway to the islands.

The transition between these two points is a full day affair that rewards those who swap the mainland jungle for the turquoise waters of the archipelago. Because Koh Rong Samloem is an island without a bridge, your journey naturally involves a combination of land transport and a sea crossing. Navigating this route requires a bit of coordination, as you need to reach the coast in time to catch the boat transfers that whisk travelers away to the island's secluded bays.

Koh Kong to Koh Rong Samloem by Bus

The most reliable way to make this trip is by booking a combined transport service that handles the logistics of getting you from the border town of Koh Kong to the island. Currently, the primary option for this route is a Coaster bus service. These vehicles are smaller than large coaches, making them better suited for navigating the winding roads of the coastal provinces while offering a more personalized environment than a standard public bus.

The journey typically costs around $38 and takes between 6 hours and 30 minutes to 7 hours to complete. This duration accounts for the drive from Koh Kong to the Sihanoukville pier and the subsequent ferry crossing to Koh Rong Samloem. Travelers can expect a scenic drive through the Cambodian countryside, passing through small villages and over bridges that span wide river estuaries before arriving at the bustling port area.

The Coaster Experience

Traveling by Coaster is a popular choice for this route because it balances speed and comfort. These vans are air-conditioned, which is essential given the tropical humidity of coastal Cambodia. While there isn't a massive amount of legroom compared to a luxury bus, the shorter wheelbase allows the driver to maintain a steady pace on the road to Sihanoukville. Once you reach the pier, the operator coordinates your transfer onto the speedboat or ferry. This seamless connection is a major advantage, as it saves you the hassle of negotiating with individual boat operators in Sihanoukville. You can easily secure your spot for this entire journey on GoAsia.cc to ensure a smooth transition from the jungle to the beach.

The final leg of the trip is the boat ride. As the mainland fades into the distance, the water changes from a murky green to a brilliant sapphire. Depending on which beach you are staying at on Koh Rong Samloem - whether it is the popular Saracen Bay, the quiet M'Pai Bay, or the sunset side of the island - the boat may make several stops. Be sure to listen for your stop so you don't end up on the wrong side of the island, as there are no roads on Koh Rong Samloem, and moving between beaches often requires another boat trip.

Tips for Traveling from Koh Kong to Koh Rong Samloem

  • Book in Advance: During the high season (November to April), the islands become very popular. Booking your combined bus and ferry ticket ahead of time ensures you don't get stranded in Sihanoukville if the boats are full.
  • Luggage Prep: Since you will be transferring from a van to a boat, and potentially walking on sand once you reach the island, pack your belongings in a backpack or a suitcase with sturdy wheels. Waterproof covers are a great idea for the boat leg of the trip.
  • Cash is King: While some resorts on Koh Rong Samloem accept cards, there are no ATMs on the island. Withdraw enough US Dollars or Cambodian Riel in Koh Kong before you depart.
  • Stay Hydrated: The journey takes about 7 hours. While the bus is air-conditioned, the heat at the pier and on the boat deck can be intense. Carry a large bottle of water with you.
  • Arrival Logistics: Most boats dock at Saracen Bay. If your accommodation is located at Lazy Beach or Sunset Beach, you may have to hike across the island (about 20-30 minutes) or arrange a private longtail boat transfer.
